Augmented/virtual realities (ARs/VRs) promise to revolutionize STEM education. However, most easy-to-use tools are limited to static visualizations, which limits the approachable content, whereas more interactive and dynamic alternatives require costly hardware, preventing large-scale use and evaluation of pedagogical effects. Here, we introduce…

University Education in Jordan has adapted completely to Distance Education due to the corona virus (COVID-19) pandemic. The study aimed to assess students' satisfaction with distance education of chemistry courses during the COVID-19 pandemic at Aqaba University of Technology (AUT). The students' satisfaction was assessed by a survey consisting…

The purposes of this study were to determine: 1) the attitudes and motivations of pre-service science teachers in learning Hess' Law using multimedia based on multiple representations (macroscopic, microscopic, and symbolic) of Hess' Law; 2) the learning outcomes of the participated pre-service science teachers after experiencing the learning…

Online multiple-choice instruments to diagnose students' understanding of science concepts are easily developed and administered to students using Google Forms. This article describes a web-based three-tier multiple-choice test for the formative assessment of students' understanding of chemical bonding. The results obtained can lead to follow-up…

Guided-inquiry experiments are an important tool for helping students develop scientific practices such as hypothesizing and problem solving. In organic chemistry, these types of experiments can help students learn how to connect the theory of the reaction to the observation and data to decide how the reaction is proceeding or if it needs…

This paper addresses the incorporation of a scaffolded infographic project into a majors' organic chemistry laboratory. Students were given the freedom to choose their topic with the stipulation that it must be relevant to both organic and green chemistry. This scaffolded project consisted of the following eight phases: (1) summarizing and…

Nuclear magnetic resonance (NMR) spectra are among the most common visualizations used by chemists in both academic and industrial settings, where they serve as both representations of submicroscopic entities and tools that support social discourse. The ability to use words to communicate about features within NMR spectra is thus an essential…

Course-based undergraduate research experiences (CUREs) integrate authentic research into undergraduate chemistry laboratories, introducing students to research while simultaneously reinforcing fundamental concepts. Despite their ubiquitous nature in bioanalytical research, few CUREs have been published applying the fundamental techniques of…

Identification and further motivation of gifted students are widely discussed among the science education community. In the context of the educational system of the Czech Republic, competitions serve as one of the main ways to identify those gifted in precollege education. In this article, we report the foundation of a team-based open-book…

The aim of this study is to examine the views of ninth grade students about 5E-based STEM learning strategies in the atomic and periodic system unit. The research was carried out with phenomenology which is one of the qualitative research designs. Purposive sampling was used and eight students participated in the study. The data was collected…

One of the complex units of chemistry education is acid-base equilibria, and learners have difficulty constructing cognitive structures on the subject. The aim of this study is to examine the conceptions of pre-service chemistry teachers with regard to weak acid-base equilibria using a diagnostic test. A qualitative research method was employed as…

Take-home examinations were utilized during the COVID-19 pandemic for upper-level analytical chemistry lecture courses. The questions were often scenarios which required the students to determine the best type of instrument to use and how to go about the experiment. Answers submitted were well thought out and detailed, showing that the students…

Chemistry faculty instructors (FIs) and graduate student instructors (GSIs) regularly engage in the evaluation and grading of student responses in formal formative and summative assessments. In this study, we identified dimensions of variation in these instructors' approaches to the evaluation and grading of students' answers. Using qualitative…

The need to develop interest in STEM (science, technology, engineering, and mathematics) skills in young pupils has driven many educational systems to include STEM as a subject in primary schools. In this work, a science kit aimed at children from 8 to 14 years old is presented as a support platform for an innovative and stimulating approach to…

Gold nanoparticles are exciting materials in nanotechnology and nanoscience research and are being applied across a wide range of fields including imaging, chemical sensing, energy storage, and cancer therapies. In this experiment, students will synthesize two sizes of gold nanospheres (~20 and ~100 nm) and will create gold nanostars utilizing a…
